1 The silicone rubber sheds adopt overall injection pressure
process, so solve the reliability of composite insulators problem
of the interface electrical breakdown. The core and the metal
fittings using the most advanced technology, high strength, good
looks, small size, light weight, corrosion-resistant galvanized
fittings, the product structure, reliable, does not damage the
mandrel, give full play to its mechanical strength.

2 Excellent electrical properties, high mechanical strength

3 Good stain resistance,and does not require
cleaning,re-contamination can run to safety.

4 Small volume, light weight. The structure is dexterous,convient
to transport and installation.

5 Silicone rubber sheds with good hydrophobic properties, the
overall structure ensures that the insulation does not get wet, no
preventive insulation monitoring tests, no cleaning, reducing
routine maintenance.

6 Good sealing performance, good resistance to corrosion, with good
resistance to aging, corrosion resistance, low temperature
resistance, suitable for -40°C~ -50°Careas.

1, ±800kVcomposite high tension insulators are widely used in ±800kV overhead transmission lines and substations

2, Dead end fittings are up to the requirements from the clients,
usually we use ball, socket, tongue, clevis for tension insulators
with forged steel. The dimensions and coupling size can be exactly
according to the specification requirements from the utilities.

3, The silicon rubber color of the insulators are also up to the
requirements from the clients and all the silicon rubber materials
past 5000 hours aging test silicon content test and hydrophobicity
test.

4, ECR core rods are used in all the insulators, so we can
guarantee a very good mechanical strength and anti-acid pollution
performance for the insulators.

5, All our insulators were type tested and design tested in
accordance with IEC61109, maximum RIV is 100µV when tested at 1MHz
and10% over nominal line ground voltage for indicated system
voltage.

6, All the ±800kV composite high tension insulators are with two corona rings

Applications:

1, ±800kV EHV DC overhead transmission power lines.

2, ±800kV EHV DC substations

Competitive Advantage:

The advantages of polymer/composite insulators over
ceramic/porcelain insulators
